 4  Severe allergies Mild lethargy - severe heart palpitations and tachycardia After six courses of allergy shots, and dozens of other prescription and over the counter medications throughout my life, Zyrtec was a Godsend for me. For the first time, it gave me a life free of itching, eczema, sneezing, asthma and recurring sinus infections, and all this with few if any noticeable side effects. However, over the past couple of years, I've experienced more and more nighttime heart palpitations, heavy heart thumping, as well as persistent tachycardia -- sometimes so much so as to keep me awake. I did not suspect it was Zyrtec until in desperation I stopped taking it. The heart symptoms completely stopped the first night. For two nights I slept like a baby. Beginning the third night after giving up Zyrtec, my allergy symptoms returned with a vengeance. I had forgotten how miserable I was before Zyrtec. I decided to take half a tablet around noon instead of before bedtime. It is better, but I am still, not sure what I'm going to do in the long run. I don't want to conk M 58 10 years

 4  allergies I took zyrtec for about a year and a half. Loved it. However, Ive had to stop taking it to have some allergy tests taken. I was violently sick to my stomach, have headaches and now cant have an empty stomach. I can only hope these symptoms go away as my activities have been SEVERLY limited. F 58

 4  intense sneezing from allergies No discernible side effects. Maybe sleepiness but not that overt. I'm hoping it's the cure for sneezing attacks so violent and long lasting that they damage my vocal chords and respiratory system due to blunt trauma. M 58

 3  Skin itching over entire body Had no obvious side effects except that I have been very anxious, angry, suspicious, and distrustfull of my wife for the past 4 years. She has accused me of not being a "happy" person for the past 6-8 years, Always used to be (or at least I thought) a happy person but was in denial over hte past 4 years thinking it was all her. After reading the posts on this site I realized that it may be the meds. quit them 6 days ago! Itching like crazy but will see what happens. Felt really weird last 2-3 days figure it's withdrawal symptoms She has accused me of not being a "happy" person for the past 6-8 years, Always used to be (or at least I thought) a happy person but was in denial over hte past 4 years thinking it was all her. Just about ready to get divorced! After reading the posts on this site I realized that it may be the meds. I quit them 6 days ago! Itching like crazy but will see what happens.

 3  adult onset spring allergies lethargy, weight gain, rash on my neck, low libido It has worked better than Claritin for my adult onset spring allergies; I originally tried "natural" remedies, which did nothing to help the sneezing, dripping and achy eyes. However since starting Zyrtec about 2 months ago, I have been needing 9-10 hours of sleep, and still have a hard time getting out of bed. And I have been gaining weight for no apparent reason, about 5 pounds in the last 2 months since I began Zyrtec this year. And a reduction in sex drive the last couple of months. And a mild itchy rash on my neck the last few weeks. As my allergies are seasonal, and they usually subside around now, I stopped Zyrtec 3 days ago and have been having trouble sleeping. Last night I lay awake most of the night. I am very happy to have found this web site and now know that these changes are because of Zyrtec. However, I would take it again next year, maybe try taking less, and taking it at night, or maybe try Claritin again because the constant sneezing and dripping and sore F 58 60 days

 2  Seasonal allergies Sleeplessness, vivid, frightening dreams, anxiety, and recently vertigo when sitting and looking down mostly. Also have had some ringing in ears and a clicking sound with some ear pressure. I have had a number of symptoms for some time that I didn't think to attribute to Zyrtec as it is now OTC and my physician recommended it for seasonal allergies and sinus pressure. After reading a lot of these other posts I'm realizing it may be the Zyrtec causing them, especially the vertigo I've recently experienced. I am going to try a gradual withdrawal to see what subsides and what ensues. F 58 365 days

 1  seasonal allergies Bad stiff neck. Continual dull forehead headache. Fatigue and just not feeling myself. I started taking zyrtec at night for my allergies thinking it would help with nighttime congestion and sleep. Woke up very tired first. After a couple of days started getting a dull headache, I seldom get headaches unless extremely congested. Then started having a stiff neck which worsen over a couple of days. In good health ans active other than allergies. I was planning to go to doctor and spouse suggested only thing I was doing different was taking zyrtec, so I stopped. After 3 days off starting to feel better. Stiff neck gone and headache less severe. Waiting to see if in a few days if all symptoms go away. My symptoms started only after taking this medicine. After reading others remarks I did have one day with some hives on my legs but dismissed it because I was playing golf and thought it was alot of bug bites. Never had adverse reactions to Claritin or flonase like this. Going back to them. These reactions should be also noted on product. And doctors should be wary of suggesting this medicine. F 58 20 days

 1  seasonal allergies with migraines itched everywhere--scalp, back, arms, chest, legs, face. Face also felt like it was burning at times--felt flushed. I started out by taking zyrtec every other day and about the beginning of the third week, I noticed I started to itch/face would burn. So, I quit taking it after four weeks and for the next couple of days, the itching was horible! So, I went back to taking claratin every other day. The second time I took claratin, I noticed that day I did not itch as much but the following day, I itched again horibly. The third time I took claratin, I did not itch at all that day but the following day, I itched although not as much. Anyway, I've taken claratin four times now (like I said, I take it every other day) but today, the day I did not take it, I DID NOT ITCH!!! I think it is out of my system and my immune system is back to normal. I will not take zyrtec ever again!! The itching was so bad it made my blood pressure go up! F 58 4 weeks

 1  Allergies COUGH, ITCHING, FATIGUE, HEART IRREGULARITIES, DIFFICULTY WITH URINATION........ among others Wouldn't recommend this drug to a squirrel! I went through 2 years of living hell until I decided enough was enough! My PC kept telling me cough isn't a related side effect..........BUBKUS! I had a nagging cronic cough, thought it was heart related but they always tell me cough isn't a heart related issue either..........BUBKUS! We have a significant family heart history and everyone of my blood relatives developed cough from their heart related issue.......makes you wonder about the quality of healthcare today. I used to go to ONE doctor for 40 years that treated everything I ever encountered........in his office 99.9% of the time.......$20 tops!! Today, you need to see 10 doctors, $$$$$$$$Thousands in unnecessary test, and generally they throw in some kind of proceedure, whether you need it or not.............it's all about the $$$$$$$$$$$$$.......average inquiry for an illness has to be in the hundreds if not thousands!!! I stopped the drug and the cough immediately subsided in a couple days time! I have significant heart issues to which I should never have been placed on this medication in the first place. It was my cardiologist that suggested stop the drug.......it's the best way of knowing and not guessing as he has done in the past with my heart medications when questionable events arose. And then there's the WITHDRAWL from this drug...........if you haven't experienced it yet, you're in for the ride of a lifetime...........weeks if not months of severe itching, to t M 58 2 years
